随着铁路运输技术的发展,作为现代化轨道结构标志之一的无缝线路,正线铺轨里程已达到6.1万km。无缝线路施工过程中,有很多复杂的技术问题,施工中稍有不慎,就会出现严重质量问题,不但体现不出无缝线路的优越性,还会引起胀轨跑道,危及行车安全。为促进现代化轨道发展,提高无缝线路的质量,根据中铁三局集团有限公司线桥工程分公司多年的施工经验,现对无缝线路施工技术进行相关的研究。
With the development of railway transport technology, as a symbol of modern track structure, the seamless track has a positive track laying mileage of 61,000 km. Seamless line construction process, there are many complex technical issues, construction inadvertently, there will be serious quality problems, not only does not reflect the superiority of seamless lines, but also cause runway expansion, endangering traffic Safety. In order to promote the development of modernized track and improve the quality of seamless track, according to the years of construction experience of the branch of Wire Bridge Engineering Co., Ltd. of China Railway Group Co., Ltd., the related research on the construction technology of seamless track is being carried out.
